General description

Heterogeneous ozonolysis of naphthalene adsorbed on XAD-4 resin has been studied using an annular denuder technique.

Application

  • Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets.
  • It was used in preparation of carbon-coated Si70Sn30 nanoparticles.
  • It was used as fluorescent probe to study the aggregation behavior of sodium cholate.
  • It was used to investigate influence of added short chain linear and branched alcohols on the binding of 1:1 complex of naphthalene and β-cyclodextrin.
